Answer:
Area: (x^2)-(9x/2)-2 3rd side=4x+9
Step-by-step explanation:
First, let's find the third side. If all of the sums add up to 7x+5, then we can easily subtract the two sides that we do have.
2x+1+x-5=3x-4
Now, you have to ask yourself what added to 3x-4 can be equal to 7x+5.
It's 4x+9 because we combine like terms. That's the third side. Now, we should follow the formula for getting the area of triangle using the side lengths:
(2x+1)(x-5)/2=area of triangle
2x*x=2x^2
2x*-5=-10x
x*1=x
-5*1=-5
Now the total is 2x^2-9x-4 when you continue to combine like terms. Now all we have to do is divide by 2. So, the area is 2x^2-9x-4/2. You can simplify that. Answer is up top.
Answer:
31x² - 2
Step-by-step explanation:
5(2x²-1)+3(7x²+1) = 5*2x² - 5*1 + 3*7x² + 3 = 10x² - 5 + 21x² + 3 = 31x² - 2
Goes like this
guess=g
n=number you are trying to find squaer root of
1. n/g=something
2. average g and something
3. (g+something)/2=e
4. n/e= sometihng
repeat steps 2 to 4 with e instead of g
115/10.7262=10.721411124163263784005519195987
average them
(10.721411124163263784005519195987+10.7262)/2=10.723805562081631892002759597994
the result is 10.723805562081631892002759597994

The equation for this is in the form y=a(1+r)ˣ, where a is the initial deposit, r is the interest rate as a decimal number and x is the amount of time. Using our information, we have the equation
8000 = 4000(1+0.053)ˣ
8000 = 4000(1.053)ˣ
Divide both sides by 4000:
8000/4000 = 4000(1.053)ˣ/4000
2 = 1.053ˣ
We will use a logarithm to solve this:
Answer:
(1/2, 0)
Step-by-step explanation:
Midpt=(x/2 +x/2) ; (y/2 +y/2)
(-1/2 + 2/2) ; (3/2 + -3/2)
(1/2 ; 0)
